Facilities

ESI’s facility, located in the heart of the industrial Midwest, is one of the largest and most modern non-hazardous wastewater pretreatment facilities in North America. Because it is accessible by both truck and rail, ESI has the ability to service customers from more than 1,000 miles away. And with the capability to process more than 1.5 million gallons of non-hazardous wastewater per day, ESI is large enough to handle multiple customers’ needs at one time.

ESI’s state-of-the-art facility, located in Indianapolis, Ind., was purchased in 1998. At the time, it was part of a large oil refinery complex. Since then, ESI has consolidated all of its operations into that facility and thoroughly modernized it for large volume capabilities. ESI leads the industry in compliance and facility qualifications with ISO 14001 certification, in addition to achieving the EPA’s Centralized Waste Treatment (CWT) compliance.
